You need to create an new Soft-eLicenser in order to reactivate any license you had on a previous Soft-eLicenser before your computer crashed. I find it helpful to run the eLicense Helper:
For Windows: http://support.steinberg.de/eLC/eLC_Ins ... Helper.exe
For Mac: http://support.steinberg.de/eLC/eLC_Ins ... Helper.dmg
*Running the eLC Helper will delete an existing Soft-eLicenser and any contained licenses it holds.
Next time you start the eLicenser Control Center the newly created Soft-eLicenser should be displayed.
Then log into your MySteinberg account.https://www.steinberg.net/en/mysteinberg.html
Next, look under My Products, and select a license you wish to reactivate by clicking on the down arrow on the right to see further Details and select the option Software Reactivation.
You will be asked to enter your new Soft-eLicenser number.
To copy a Soft-eLicenser number, open the eLicenser Control Center (eLCC) which can be found in the "Program Files" (Windows) or "Applications" (Mac) folder. Select "Registration" from the top menu, choose the 20-digit Soft-eLicenser number and click on "Copy Serial Number".
If you registered the previous license it will auto fill your previous registered activation code in the old activation code field. Once the new Soft e-Licenser and old activation code fields are complete select Reactivate. This will provide you with a new 32 character activation code(s) for any license(s) you need to reactivate.
